The term ____________________ means the lack of muscle coordination during voluntary movement.

tia_tia [17]

The term <u>Ataxia</u> means the lack of muscle coordination during voluntary movement.

Poor muscle control that results in awkward voluntary movements is known as ataxia.
It might make it difficult to move your eyes, speak, or walk steadily. It might also make it hard to coordinate your hands.
Ataxia is typically caused by injury to the cerebellum, which regulates muscular coordination, or its connections.
Ataxia is typically brought on by damage to the cerebellum, a region of the brain, although it can also be brought on by injury to the spinal cord or other nerves.
The spinal cord, which extends the length of the spine and connects the brain to every other part of the body, is a lengthy bundle of nerves.

The net primary productivity is usually more than 80% of gross primary productivity.

fomenos

Answer:

b. False

Explanation:

As GPP stands for the gross primary productivity, it's the total amount of energy produced in the process and the NPP is the net primary productivity. NPP is the difference between the GPP and the energy used by the producer for the process of respiration.

GPP is a continuous and ongoing process that consumes the energy as compared to the NPP that store energy and not being used. Thus, GPP can affect NPP but NPP does not affect GPP.

For example, GPP is completely being dependent on the chlorophyll content of the plant, but NPP is independent of that content of chlorophyll.

In a sample of cells, the DNA content immediately following mitosis is measured and is equal to 10 picograms of DNA per nucleus.

Rasek [7]

Answer:

1. At the end of S phase- 20 pg DNA

2. At the end of G2 phase- 20 Pg DNA

Explanation:

The cell before undergoing M phase undergoes the steps of interphase that is G₁, S and G₂ phase.

During S phase, the process of cell replication takes place which replicates the DNA as a result of which the amount of DNA doubles. This DNA amount is reduced to half during the anaphase stage of M phase.

In the question since the amount of DNA is 10pg therefore the amount will be double during S phase and becomes 20 pg and will remain 20 pg until the DNA is distributed therefore at the end of G₂ phase Will remain the 20 pg.

6. A scientist measures the circumference of acorns in a population of oak trees

melisa1 [442]

Answer:

6. 2 cm

8. Greater than 2 cm and less than 2 cm

Explanation:

Complete Question

6. A scientist measures the circumference of acorns in a population of oak trees and discovers that the most common circumference is 2 cm. What would you expect the most common circumference(s) to be after 10 generations of stabilizing selection?

-2 cm

-Greater than 2 cm or less than 2 cm

-Greater than 2 cm and less than 2 cm

-Can't tell from the information given

8. Refer to question 6, but this time answer what you would expect after 10

generations of directional selection.

-2 cm

-Greater than 2 cm or less than 2 cm

-Greater than 2 cm and less than 2 cm

-Can't tell from the information given

Solution -

6. In an stabilizing selection, the average trait of a given population is favored over extreme values. Hence, it can be said that one specific trait is over presented in a given population. For example – uniform human birth weight, number of eggs a bird lay etc.

Here in this case if most common circumference is 2 cm , then the tree population will try to have this trait as a stabilizing trait.

Thus, option A is correct

8. In a directional selection, the genetic variation decreases as per the environmental change. And hence the average trait will not be selected. Instead traits either higher or lower the average values will be preferred.

Thus, option C is correct
